Crystal structure of transcriptional regulator protein from Thermotoga maritima.

Overview

The crystal structure of a putative transcriptional regulator protein, TM1030 from Thermotoga maritima, a hyperthermophilic bacterium, was, determined by an unusual multi-wavelength anomalous dispersion method at, 2.0 A resolution, in which data from two different crystals and two, different beamlines were used. The protein belongs to the tetracycline, repressor TetR superfamily. The three-dimensional structure of TM1030 is, similar to the structures of proteins that function as multidrug-binding, transcriptional repressors, and contains a large solvent-exposed pocket, similar to the drug-binding pockets present in those repressors. The, asymmetric unit in the crystal structure contains a single protein chain, and the twofold symmetry of the dimer is adopted by the crystal symmetry., The structure described in this paper is an apo- form of TM1030. Although, it is known that the protein is significantly overexpressed during heat, shock, its detailed function cannot be yet explained.
